5. A processing method, comprising:
calculating, as a first calculation, performance of a plant before introduction of a part and the performance of the plant after the introduction of the part for each of combinations of a plurality of loads in the plant and a plurality of atmospheric temperatures around the plant, the plurality of atmospheric temperatures being detected by a temperature sensor;
storing a data table indicating a percentage of an operating time of the plant for each of the combinations;
calculating, as a second calculation, based on a calculation result of the first calculation and the data table, how much the performance of the plant is improved compared with the performance before the introduction of the part in a case where the part is introduced and the plant is operated at the percentage indicated by the data table;
replacing a first part with a second part for changing the performance of a power generator, the first part being in the plant, the second part being a part that is determined based on a result of the second calculation and introduced into the plant; and
outputting power from the power generator to a load, the power being in accordance with the load.
